Remove Hot Pixels was one of my first idea (as its one of the few filters where i actually know whats its good for).

Just tried a Selective Gaussian Blur with a Radius of 30 and Delta the default 50. That helps but makes it look a bit dull...not sure if i like that.
I think selective Blur is the filter that a lot of smartphone users apply and can make you look like Odo from 'Deep Space 9' when overdone

Also tried the G'MIC variant Smooth [bilateral] but that smeared the contours into blobby territory.
Smooth [anisotropic], my default filter for improving texteffects, doesnt bring it either

Agreed, even at 1% Spacing, its not optimal.
Tbh, i dont fully understand the effect - why it looks so different on the letter p for example. I guess its the angle ?
